what happens if the arctic melts

It is melting. : http://dne.ws/1Lm48kc Climate change is causing the ice sheets to melt at an alarming rate. Pig guts were thrown, Video of 4 police officers beating Black man emerges, Read: Arctic's 'last bastion' of sea ice is breaking up for the first time, Read: Arctic permafrost is melting so fast it's damaging scientists' equipment, Inside the military base at the heart of Putin's Arctic ambitions, Read: Judge rules Trump executive order allowing offshore drilling in Arctic Ocean unlawful. Yahoo is part of Verizon Media. 5.2 What will be the impact on marine fisheries? In the short term, this creates something of a nutrient injection that jump starts the cycle of life in the ocean. The Arctic is melting faster than at any time in at least the last 1,500 years, according to climate scientists. Melting Greenland ice sheet raises sea levels. If we keep burning fossil fuels indefinitely, global warming will eventually melt all the ice at the poles and on mountaintops, raising sea level by 216 feet. The US has not signed on to the Law of the Sea treaty, the UN guidelines on how countries use our oceans, and Secretary of State Mike Pompeo recently hailed the economic opportunities presented by shrinking levels of sea ice opening up shipping lanes and a wealth of natural resources. The uncertainty is how fast it happens. Which Country Will Be Under Water In Our Lifetime? First, ice is white and the ocean is…. 2016 saw some of the most extensive sea ice loss in recorded history. These waters might look barren, but they are hugely productive when it comes to the building blocks of ocean life. The investigation will provide students an opportunity to observe over time and compare how the melting of different types of ice in the Arctic and Antarctic will affect sea-level rise. Melting land ice, like mountain glaciers and the Greenland and Antarctic ice sheets, will change the Earth’s rotation only if the meltwater flows into the oceans. That means almost half of Australia would perish and the rest flooded completely. 2. Sea ice is rapidly disappearing as a result of climate change and warming seawater temperatures. In this warmer water, away from the ice, they found significantly less phytoplankton. Here, the scientists spend days working on top of the precarious ice floes, keeping a watchful eye out for polar bears while drilling into the ice to measure its thickness. As Arctic Sea Ice Disappears, What Happens to Ecosystems? Ice loss is a function of natural climate variability and anthropogenic warming caused by increased atmospheric CO 2 concentrations. The writing is on the wall that human's will have to adapt to a very different world as ice melts and oceans rise. There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted. If it melted sea levels would not be affecte­d. As the ice melts, the Arctic area becomes more accessible -– as does the 90 billion barrels of oil the U.S. Geological Survey estimates are beneath the Arctic Ocean. But warmer temperatures in the Arctic are causing another type of ice to disappear as well: land-based ice in Greenland. It is one important reason why the Arctic is warming faster than the rest of the planet. As the sea ice melts, ice algae and phytoplankton are released into the sea. The Arctic's frozen ground contains large stores of organic carbon that have been locked in the permafrost for thousands of years. As the region’s once abundant ice melts, giving way to a less reflective surface, the Arctic heats up faster—now at a rate that is double the rest of the planet. "We can put a deal in place that the status quo goes on or we can put a deal in place that has teeth, that will allow us to designate areas in the high seas for fully protected marine reserves," says Sune Scheller, Greenpeace's expedition leader. Negotiations towards a Global Ocean Treaty at the UN are under way and Greenpeace is part of a broader coalition that is campaigning for legislation that would see 30% of our oceans protected by 2030. "This warm water is at the surface as it comes up [from the south] and then it drops under the ice as it goes into the Arctic Ocean," says Wagner. Sea ice loss will impact us all, in ways that science is racing to understand. But it may prove to be challenging, with some powerhouse nations, including Russia and the US, looking at short term economic gains at the expense of the planet's future. Arctic marine fisheries … Once all ice is melted and added to the global oceans our seas would rise by 216 feet as compared to the current level. "And the risk of not doing that is pushing the marine ecosystem over the edge. "It isolates the ice from the hot devil water sitting at the bottom waiting to come up" Wagner explains. The team's study confirmed their expectation. But this April saw a record loss of sea ice across the Arctic. It is one important reason why the Arctic is warming faster than the rest of the planet. "The layer that is under the ice has been coming up closer to the surface and melting the ice from underneath.". The underbelly of the ice teems with zooplankton -- tiny crustaceans that feed on the phytoplankton. As the ship heads further south, we come across red streaks of blood across the ice, the bloody aftermath of a polar bear kill. "It has definitely thinned in this area, it has thinned everywhere" says team leader, polar physicist Till Wagner, of the University of North Carolina Wilmington. And being in direct contact with the warming waters of the ocean, sea ice will be the first form of frozen water to disappear. The consequences of climate change can be weird and apocalyptic. Melting land ice, like mountain glaciers and the Greenland and Antarctic ice sheets, will change the Earth’s rotation only if the meltwater flows into the oceans. With our planet continuing to warm due to greenhouse gas emissions, we expect to see years in the not-too-distant future where Greenpeace is traveling from the Arctic to the Antarctic to highlight the threats facing our oceans and part of its campaign for ocean sanctuaries. What the sea ice melt does to the ecosystem, and to us, is at the heart of this study. ( Read about how unexpected changes are occuring in … See our study on Fisheries. 2. If we keep burning fossil fuels indefinitely, global warming will eventually melt all the ice at the poles and on mountaintops, raising sea level by 216 feet. If you have ice floating in the water, it displaces some liquid water. It’s not “if” but when. not white. As we lose more ice more quickly and see more rapid permafrost melt, we will start seeing the worst climate change predictions come true. A team of interdisciplinary scientists is here on a study facilitated by Greenpeace, at the start of the environmental group's nearly year-long pole-to-pole expedition. After a recent excursion to the Arctic , researchers made a seriously shocking — and truly devastating — discovery regarding just how quickly the Arctic's ice is melting . In the short term, this creates something of a nutrient injection that jump starts the cycle of life in the ocean. Enjoy Miami and Shanghai While They’re Here. "And then right below there is this warm water, that is almost 3.5 degrees and this is the warm Atlantic water" Cape adds. Measuring the thickness and density of a recently extracted ice core. Faster melting tends to become a self-reinforcing system in the Arctic. 6 What would happen to Australia? Faster melting tends to become a self-reinforcing system in the Arctic.

Continued burning of fossil fuels will destroy life faster. If you have ice floating in the water, it displaces some liquid water. The ice floats on the Arctic Ocean. This effect, known as “Arctic amplification”, has consequences for nearby land ice, too. Most of the Atlantic coast, Florida, and the Gulf Coast will be underwater. "It's tragic to hear something like that and I think this is an extreme case of cherry picking because obviously you can find small individual good things about climate change but in the broad perspective the negative downside of this to us as humans, the environment, the ocean, will outweigh the small potential benefits substantially," says Scheller.
